Phys.org / Scientists harness nature's chirality bias to design series of complex mechanically interlocked molecules
In nature, molecules often show a strong preference for partnering with other molecules that share the same chirality or handedness. A behavior that is quite evident in the phenomenon known as homochirality-driven entanglement, ...
Phys.org / Underestimated wake: Shipping traffic causes more turmoil in the Baltic Sea than expected
Commercial shipping not only affects the Baltic Sea on the surface, but also has a significant impact on the water column and the seabed. A study by the Leibniz Institute for Baltic Sea Research Warnemünde (IOW) and Kiel ...
Medical Xpress / Human stem cell lines offer new resource to help study HIV progression
King's College London researchers have created a unique collection of human stem cell models that could help to uncover why HIV leads to different outcomes in different people. The research was carried out by Dr. Nathalia ...
Phys.org / Yangtze River fishing ban halts seven decades of biodiversity decline
The Yangtze River Basin, a global biodiversity hotspot, has endured severe ecological degradation over several decades due to intense human activity, leading to a marked decline in aquatic biodiversity. In order to halt this ...
Phys.org / Physicists develop new protocol for building photonic graph states
Physicists have long recognized the value of photonic graph states in quantum information processing. However, the difficulty of making these graph states has left this value largely untapped. In a step forward for the field, ...
Phys.org / Where'd you get that frog? Study traces illicit online amphibian trade
Keeping amphibians as pets offers hobbyists an opportunity to connect with the non-human world, often increasing interest in conserving animals in the wild. But there's a dark side to the amphibian trade, according to a study ...
Medical Xpress / Menopause, hormones and the brain: How hormone therapy could help protect against Alzheimer's
As dementia and other neurodegenerative diseases become more common worldwide, researchers are searching urgently for ways to protect the brain as we age. One area attracting growing attention is hormones, particularly the ...
Tech Xplore / New sound-based 3D-printing method enables finer, faster microdevices
Concordia researchers have developed a new 3D-printing technique that uses sound waves to directly print tiny structures onto soft polymers like silicone with far greater precision than before. The approach, called proximal ...
Phys.org / The shape of skis makes the biggest difference in maneuverability
From the biathlon to the slopestyle to the giant slalom, raising a ski above your head after crossing the finish line is the triumphant Olympic skier's standard celebration. But why do the skis of the competitors in each ...
Phys.org / Nature's 'engine is grinding to a halt' as climate change gains pace, says study
Many ecologists hypothesize that, as global warming accelerates, change in nature must speed up. They assume that as temperatures rise and climatic zones shift, species will face local extinction and colonize new habitats ...
Medical Xpress / Men lose their Y chromosome as they age: Scientists thought it didn't matter—but now we're learning more
Men tend to lose the Y chromosome from their cells as they age. But because the Y bears few genes other than for male determination, it was thought this loss would not affect health. But evidence has mounted over the past ...
Tech Xplore / Counter-drone technologies are evolving—but there's no surefire way to defend against drone attacks
When the Federal Aviation Administration closed the airport in El Paso, Texas, and the airspace around it on Feb. 10, 2026, the cause was, ironically, the nearby use of a technology that could be key to keeping airports and ...
